I guess one of the isues with me will be diif. in noise. When I shoot aluminums I shoot a 2315 just because it is noticably quiter than a 2413, last years arrows just might be ticket with my Pat DC, I imagine a 483 arrow out of a 70lb Dually will pack some pretty good punch, another thing, are the A/C/C shafts noticably quiter than say an all carbon shaft of the same weight? Just wondering if the combination of materials has any effect.
